Cerinthe major purpurescens, Cerinthe minor auriculata
Annual
Start seed indoors 10 weeks before last frost. Cerinthe is quite a large seed and is best sown individually. Sow on to very moist compost and cover to a depth of 10 mm with vermiculite. Propagate at 18 to 20°C and germination should begin to take place after about 10 days. Continue to maintain a temperature of 15°C for approximately 2 weeks after germination at which point it can be lowered to 10°C. Plant outdoors after last frost date 16cm (24") apart into a full sun location.
